Set the graphic card, before the first blender start. (Virtual Linux System)
Could it be, that the issue is caused, because blender required some sound card?
No, it is probably cause by an indirect rendering setting for the graphic card driver similar as mentioned here. The warning ALSA lib confmisc.c:767:(parse_card) cannot find card '0' is probably caused by a missing sound device, but can suppressed by ./blender -noaudio.
